Hearing the shape of a Dirac drum: Dual quantum Hall states on curved surfaces

This paper demonstrates that the quantum Hall spectra of Dirac surface states on curved 3D topological insulator nanowires comprise two distinct classes—one scaling with the magnetic field and another intimately tied to the wire's geometry—and reveals a duality where specific curved surfaces possess reciprocal partners with dual spectra, including a cone-shaped nanowire whose partner exhibits magnetic-field-independent states.

Coulombic control of charge transfer in luminescent radicals with long-lived quartet states

This study establishes design rules for efficient quartet generation in luminescent radicals by demonstrating that Coulombic tuning of electronic coupling via molecular topology controls charge transfer pathways, enabling high luminescence yields dominated by long-lived quartet states.

Electronic correlations in magnetized helical edge states coupled to s-wave superconductors

This paper theoretically investigates how electron-electron interactions influence correlation functions and spin transport in one-dimensional magnetized helical edge states coupled to s-wave superconductors, revealing distinct regimes where superconductivity and magnetic fields differentially enhance or suppress various pairing and density-wave correlations depending on the interaction strength.

Coherent Control of Quantum-Dot Spins with Cyclic Optical Transitions

By leveraging light-hole mixing to create a highly asymmetric lambda system and compensating for differential Stark shifts, the authors demonstrate simultaneous high-fidelity electron-spin control and high-cyclicity optical readout in semiconductor quantum dots, overcoming a key limitation for quantum communication technologies.

Layer-tunable Hubbard bands probed via moiré excitons in MoSe2_2/WS2_2 heterostructures

This study demonstrates that vertical electric fields can deterministically tune layer-specific Hubbard parameters in dual-gated MoSe2_2/WS2_2 heterobilayers, enabling the quantitative extraction of layer-dependent on-site Coulomb repulsions and the stabilization of generalized Wigner crystal and stripe phases by shifting the ground state to the WS2_2 layer.

Defect Engineered 2D MoS2 Materials for ML-enabled Neurotransmitter SERS Detection

This paper demonstrates that defect-engineered 2D MoS2 monolayers, created via soft plasma etching to introduce sulfur vacancies, enable highly sensitive and selective SERS detection of catechol-containing neurotransmitters like dopamine and epinephrine down to sub-nanomolar concentrations, with machine learning algorithms achieving 100% accuracy in distinguishing their spectra.

Long-lasting Topological Entanglement in a Monitored Rashba Nanowire

This paper demonstrates that the topological value of disconnected entanglement entropy in a monitored Rashba nanowire persists for a time linear in system size despite boundary dissipation, a phenomenon driven by the interplay between non-conserved particle number, topological manifold degeneracy, and the eventual poisoning of ballistic quasiparticles.

Residual orbital magnetization governs the anomalous Hall effect in altermagnets

This paper demonstrates that residual orbital magnetization, generated by the interplay of local crystal fields and spin-orbit coupling, intrinsically governs the anomalous Hall effect in altermagnets through the generalized Středa relation, challenging the view that their small remanent magnetization is irrelevant to transport phenomena.
